Description:
Loose tubes (or some fillers) stranded around the metal central strength member, bound by corrugated longitudinal steel tape with outer PE jacket.  The tube is made of good tempertature property material, a number of single or multi-mode fibers double-coated are contained in the loose tube. 

Features:
Accurate fiber excess length ensures good mechanical and temperature performance.
High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fiber.
Specially designed compact structure is good at preventing loose tubes from shrinking.
The central strength member makes use of high Young's modulus phosphatized steel wire.
The loose tubes and all interstices of cable core filled with moisture-proof and water blocking compound ensure no longitudinal water ingress.
Longitudinal steel tape bonding to PE jacket ensures not only radial moistureproof but also reinforces the crush resistance.
Polyethylene outer jacket can resist deterioration from ultra-violet (UV) rays.
